This charger has a unique mode for recharging LiPo batteries. A feature of these batteries is that they read 0 to manage not to completely discharge. This charger should read the voltage and wakes to charge when this condition is encountered. So far as used the charging is normal. I will update this recommendation once I see the charger go off and wake to recharge the battery. Recommended for versatility.

I bought this for my two parallel 12v 100 Ah batteries. It works great. As the product photos show it is a very simple charger. No fancy screens. It charges both batteries at their full capacity (the BMS limits a full 20 amp charge. The cables included are good quality and are easy to connect. The little carry handle is really nice.Recommended.

This charger has an impressively solid metal chassis and good quality cables. No bells, whistles, or options, which is actually good. It only works with LiFePO4 batteries - hook it up and it just does it's job. Seems to charge fast, and shuts down cleanly when done. Much better than one I previously purchased from Amazon, with LCD displays and multiple options, but I never quite trusted was giving a full charge.

This runs surprisingly cool thanks to the built-in cooling fan and aluminum housing, even during long charging sessions. The LED status indicators are easy to understand at a glance, and the dual connection options are super convenient for both permanent setups and quick hook-ups.At this price point, especially with the included connectors and protections, it's a solid investment and well worth every penny for anyone running a 12V LiFePO4 system.

Really like the charger! Nice heavy duty cables, and really like the status light indicating the different stages of charging, AND the handle on the unit. New Anderson connectors didn’t quite fit my old Anderson connectors. With a small screw driver I was able to change out the connector casings to match my boat. There appears to be a small mistake in the Owners Manual, which I brought to the attention of Tech Support. They said they would update the manual and send me a new digital copy. I had to contact Tech Support thru Amazon website. Not sure how I manage to do it, but hopefully If I need to in the future, it would be more straightforward…

Great support from this seller. Better wiring size for needed amperage than other sellers. I would buy again!
